What is the most Caucasian last name?

The most Caucasian last name, meaning the most common last name among Caucasian or white Americans and Europeans, depends on region, but in the United States, the most common surnames among white Americans include Smith, Johnson, Williams, Brown, and Jones, which are of English origin. Smith is the most common last name in the US overall and is predominantly held by Caucasians of English ancestry, meaning blacksmith.
